305-026-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-026-520-568 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 26 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and is rated for 5 A continuous current. Constructed with a green thermoplastic polyester housing, it operates within a temperature range of -40°C to +105°C. This vertical header employs solder pin termination for secure panel mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified card edge boards.
• Gold-plated copper alloy contacts provide corrosion resistance and conductivity.
• Thermoplastic polyester insulation ensures stable performance across wide temperatures.
• Vertical panel mount style facilitates structured hardware integration.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required current rating and operating temperature specifications for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and thermal stability for high-reliability environments. Verify that the target circuit board thickness falls within the specified mechanical acceptance range. Ensure sufficient clearance for the vertical orientation during chassis design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-026-520-568 specifically provides a 26-position configuration. It shares common family characteristics such as the 3.96 mm pitch and gold contact options found throughout the series.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for direct equivalents. Cross-reference compatible parts from other manufacturers only if mechanical dimensions and electrical ratings match precisely. Verify that alternative components support the same dual-edge interface and panel mount requirements.
